Description

Progressive die with gasket inner hole deburring pressing die

Technical Field

The utility model belongs to the technical field of the punching press, especially, relate to a modulus of continuity with gasket hole burring moulding-die.

Background

The gasket is one of the parts commonly used in production and life, the inner hole is punched in the first step and is cut and formed in the second step through two-step punching, when the thickness of the gasket is thinner to 0.5mm, a customer requires that the inner hole has no burrs and flatness, the deformation can be easily generated through a conventional vibration deburring mode, if a set of deburring working procedures is independently added, the gasket is thin, and the process cost is wasted because the gasket is placed in a new deburring and edge pressing die.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a modulus of continuity with gasket hole burring moulding-die can flatten gasket hole burr limit in process of production, and is efficient, saves manufacturing cost.

The utility model discloses a following technical scheme realizes:

a progressive die with a deburring pressing die for an inner hole of a gasket comprises,

the punching mechanism comprises an upper die, a lower die and a punching mechanism, wherein the upper die is provided with a punching male die and a blanking male die;

the lower die is provided with a punching blanking port and a cutting blanking port, the punching blanking port is matched with the punching male die in position, and the cutting blanking port is matched with the blanking male die in position;

and the lower die is also provided with a deburring male die, and the deburring male die is arranged between the punching blanking port and the cutting blanking port.

Furthermore, the height of the deburring convex die higher than the upper surface of the lower die is the same as the thickness of the gasket to be produced.

Further, the outer edge of the deburring convex die is provided with a 45-degree chamfer.

Further, the outer diameter of the deburring convex die is the same as the diameter of the punching convex die.

Furthermore, the punching male die, the blanking male die and the deburring male die are positioned on the same vertical symmetrical surface.

The utility model has the advantages that;

1. the utility model discloses an increased the process of a deburring terrace die, realized the burring continuous processing of hole in the gasket production, it is long when having saved technology, improved production efficiency.

2. Through with the height that the deburring terrace die exceeds the lower mould upper surface with treat that production gasket thickness is the same, can be so that behind the burr back-pressure hole, keep the roughness of gasket.

3. Through setting up 45 chamfers on outer edge for the deburring terrace die gets into hole woollen more easily.

4. The outer diameter of the trimming male die is the same as the diameter of the punching male die, so that the stability of the diameter of the inner hole of the gasket is ensured.

5. The punching male die, the blanking male die and the deburring male die are located on the same vertical symmetrical surface, so that the stability of the continuous die during working is ensured.

Fig. 2 is a schematic view of the structure of the utility model during operation.

Figure 3 is the utility model discloses gasket deformation schematic diagram among the stamping process.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1~2, a progressive die with a gasket bore deburring die, comprises,

the device comprises an upper die 10, wherein a punching male die 101 and a blanking male die 102 are mounted on the upper die 10;

the lower die 20 is provided with a punching blanking port 201 and a cutting blanking port 202, the punching blanking port 201 is matched with the punching male die 101 in position size, and the cutting blanking port 202 is matched with the blanking male die 102 in position;

wherein, still be equipped with the deburring terrace die 203 on the lower mould 20, the deburring terrace die 203 set up in punch a hole blanking mouth 201 with cut between the blanking mouth 202.

In a further scheme, in order to ensure the flatness of the gasket, the height of the deburring convex die 203 higher than the upper surface of the lower die 20 is the same as the thickness of the gasket to be produced.

Further, in order to enable the deburring convex die 203 to enter the inner hole more easily, the outer edge of the deburring convex die 203 is provided with a 45-degree chamfer.

Further, in order to ensure the stability of the inner hole, the outer diameter of the deburring punch 203 is the same as the diameter of the punching punch 101.

Further, in order to ensure the working stability of the progressive die, the punching male die 101, the blanking male die 102 and the deburring male die 203 are located on the same vertical symmetrical plane.
